APIs (Application Programming Interfaces) are essential for enabling communication between different software applications. They define the methods and data formats that applications can use to request and exchange information. Python provides several frameworks to build APIs, including Flask, Django REST Framework, and FastAPI.
Using Flask to Build APIs
Flask is a lightweight and flexible Python web framework that is easy to use for building APIs. Here is a basic example of creating an API using Flask:
from flask import Flask, jsonifyapp = Flask(__name__)@app.route('/api', methods=['GET'])def home():return jsonify({'message': 'Hello, World!'})if __name__ == '__main__':app.run(debug=True)Copied!âś•CopyThis script creates a simple API that returns a JSON response when visited at the route /api.
